  • Does anionic polyacrylamide treatment improve seedling emergence and growth?
  • Wallace A (1987) Anionic polyacrylamide treatment of soil improves seedling emergence and growth. HortScience 22:951 Wallace A, Wallace GA (1986) Effects of soil conditioners on emergence and growth of tomato, cotton, and lettuce seedlings.
  • What causes nonionic polyacrylamide adsorption?
  • Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces , whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [1, 80].
  • Does Pam adsorption affect clay particles aggregation and heavy metal ions?
  • The literature studies on the impacts of PAM adsorption on clay particles’ aggregation and heavy metal ions’ accumulation in soil environments have been also presented. Polyacrylamides (PAMs) are group of water-soluble, synthetic polyelectrolytes derived from acrylamide monomer in polymerization process [1, 2, 3].
  • Does polyacrylamide affect soil erosion and field runoff reduction?
  • Fox and Bryan , Stern et al. , and Smith et al. determined the influence of PAM presence on soil erosion and field runoff reduction. Soils treated with polyacrylamide maintain their original physical state in water erosion conditions.
